yAs preferably constructed the machine is 'providedwith a suitablesupporting frame 1 and a table 2 thereon. An arm 3 is rigidly fixed on the normal rear portionof the table i and extends upwardly and forwardly above the forward portion of the table, the top of the arm near the forward end thereof having a fulcrum stand 4 thereon provided with a pivot 5. The forward end of the arm is provided witha, guide-head 6 having a cap thereon. .A.-header 8 of novel construction' is provided which is vertically Patented June 6, 1916.

Application filed November 4, 1913. Serial No. 799,230. 3 i I guided in. the guide-headabove the forward portion of the table and is provided with a device 9 that directlyengages and controls the. header. The bottom or under face of 'theheaderhas a socket 10- therein to receive the end of a rivet, the bottom of the header having also a concave depression 11 adapted for upsetting the ends of the rivets. In some casesthe depression is in a slightly projecting heel formed on the bottom of the header, as shown in Figs. 1 and. 5, ,to' constitute a guideagainst which to place work to be riveted; in other cases the header has a plane'surface on its bottom, as in Fig. 6. A pivot 12 is carried by a lever 13 which is mounted on the pivot 5 and in the present case fixed to the device 9 s0 that..the lever moves and controls the header. Preferably the device 9 is rounded on its top and bottom and operates in an opening formed in the header. A connecting rod 14 is connected to the pivot 12 and has apivot 15 connected thereto to which is connected a controllin 'lever 16 that is supported on a pivot I ,mounted on the 'frame 1.' The lever16, as

will be seen, is supported between its ends and is provided with a pivot 18 between its forward end and its supporting pivot 17. A connectingrod 19 is provided which is relatively shorter than the connecting rod 14'and is connected to the pivot I8 and extends upward therefrom, the upper portion of the connecting rod 19 being provided I with a pivot 20 to which a punch ram lever 21 is connected, the latter being mounted on a pivot 22 suitably supported below the table 2. The lever 21 being horizontally arranged and supported between its ends it.

extends forward beyond its support and has a horizontal slot 23 therein that receives.

- downward nearlvto the anvil bar so as to force the plates 27 on the anvil bar, and as will be seen the ram 24 is in alinement with the socket 10.

The lever 16 which operatesand controls the header lever 13 andthe ram lever 21 may be operated and controlled by various power means, as is obvious, the forward portion of the lever 16 preferably being provided with a pivot 29 to which a link 30 is connected, the latter having a pivot 31 connected thereto with which a foot-lever 32 is connected between its ends, one end of the foot-lever being connected to a pivot 33 supported by the frame 1 of the machine. A retractingspring 34 is'connected to the foot-lever and also tothe frame, and the forward portion of the foot-lever has a treadle or foot-plate 35 thereon.

-For automatically feeding the' rivets forward on the table to the rivet-stop 26 a feedrod'36-is provided which is arranged horizontally on the table and provided with a sheave 37 aboutwhich a cord or cable 38 is placed, one end of the cord being secured to an eye 39 with which the under side of the arm 3 is provided, the cable extending downward through the table over a guide sheave 40 that is supported under the table. The lowerend of the cord is provided with a-weight 41 that acts to move the feed-rod forward, the latter being readily retracted by hand. Preferably the anvil bar 28 is composed of sections secured upon'the table 2 by means of screws 42, and a guide channel 43 is conveniently provided'in the under side of the anvil bar to guide the rivets on their heads and receive the feed-rod 36, the latter being provided with guides 44 mounted on the table 2. The top of the table has a groove 45therein in which the sheave 37 operates, and a slot 46 extends from the groove and through which the cord 38 operates. In the feed-channel 43 are horizontal guide bars 47 between which the bodies of the rivets are guided while the heads of the rivets pass under the guide bars.

is in retracted elevated position, as indicated" in Fig. 1. The sheets that are to be riveted together are placed upon the anvil bar 28 and, force being applied to the treadle 35 the Various levers are caused to move, with the result that the header 8 is brought down upon the plates 27 and the ram 24 caused to force a rivet upward through the plates and into the socket 10, as seen in Fig. 5, after which the ram and the header are permitted to be retracted through the action of the spring 34. The sheet containingthe rivet, the end of the latter being withdrawn from the socket, is shifted tor-bring the endof the rivet under the depression 11, after which the treadle is again operated and the header forced down so as to upset the rivet and form another head thereon in the depression 11, thus securing the plates together, and at the same time if a rivet is placed upon the ram 24 it is forced through other portions of the plates, as in Fig.6, so that the work is performed rapidly.
